To access a segment not pointed to by one of the segment registers, a program must first load the segment selector for the segment to be accessed into a segment register. Each of the segment register is associated with one of three types of storage: code, data or stack (will be explained in detail later).or example, placing a programâs stack in a separate segment, prevent the stack from growing into the code or a data space and overwriting them. Placing the OSâs or executiveâs code, data and stack in separate segments also protect them from application/program and vice versa.
